I know most people dislike bad drivers on the road, but i cant stand people that dont interpret what is goin on around them... like watching a few cars ahead instead of just the one in front of you because all of a sudden everyone is braking hard because they "didnt expect the sudden stop" or people coming to a complete stop when merging lanes... Just pick a gap and bloody go... the next person isnt going to ram you... but the person you just stopped in front of might...
Oh and the worst thing would have to be people in the right "fast" lane just cruising along next to someone at the same speed... THE RIGHT LANE IS FOR OVERTAKING... if your not overtaking, get out of the right lane...

When you leave home for a easy and gentle drive in the bush,next thing the track you wanted a little peek at, gets real bad,you cant reverse back, and ahead you seemingly have hours of the unknown in front of you
